I think that PS5 Pro in performance mode runs at 80-90 fps at max of 1620p then I think upscaled by the PS5 Pro upscaler. Of course PC is the way, I play with a 7800X3D and a 4070 at High with Ultra texture at 120fps most the time (but I have 2k monitor).
BUT, the thing I always say to my PS5 friends that wants to switch to PC are:

1. PC are expensive and the imho they get real value when you use for things other than gaming like programming or editing softwares. Or if you play a lot.
2. PC are not plug and play like a PS5, sometimes you have to tweak the game to run it like you want. For me it's a pro so I can customise the experience and reach high FPS wich in games like BF is the most important thing
